Hello everyone,
I have reserved this plot of land, see attachment, and have already received a cost estimate from the construction company. The builder plans to construct a house on a slope on the plot, see picture in the attachment. This costs about 18,000 euros more than a house built only on a slab foundation. Additionally, the earthworks have been estimated at 40,000 euros, including drainage, additional foundation work, etc. Unfortunately, this is a total of 40,000 euros more than I had originally planned. What do you think about this cost breakdown? Is it really that expensive?

And also make sure to include an extra budget for the landscaping when building on a slope. Just the staircase and wall in your animation will cost a significant amount.
I also find it quite noteworthy that you’re questioning the contractor’s cost estimate. They have no interest in quoting you excessively high costs to discourage you from the project. It’s better to assume these are the minimum costs, and that additional expenses are likely to come. Generally, the contractor is more interested in estimating the project favorably for you. If later on you don’t have enough left for the landscaping, that’s not their concern and they don’t incur any loss from it.

Good thing you only reserved the plot. If you want a house with a slab foundation, you will need to keep looking. This is clearly a plot suited for a partial basement (a split-level design might also work, but not a slab foundation).

The road level where you are is going to be raised at least another 0.8 to 1.2 meters (about 2.5 to 4 feet) in the future (see the utility channels). You should study the development plan very carefully, especially regarding a) current ground heights; b) final road elevation; c) reference points for eaves and ridge heights; d) the scope of possible terrain modifications. Also, e) there are still tricky details concerning the average wall height of a garage built on the boundary, and remember f) especially when dealing with slopes, you need to sort out drainage before the property boundary. At least, you already have neighbors with rights shown in the image, so it’s worth having a chat with them.

A slope does not rule out a slab-on-grade foundation. I also consider our house to be a slab-on-grade house, even though the ground floor supports the slope. Why add a basement underneath?
From below, it looks like a raised villa, and from above like a single-story house.
A slope house always has at least one living floor in contact with the earth and one side without windows.
If the original poster doesn’t have significant financial reserves, the plot is not suitable. There is already a five-figure shortfall even without landscaping or contingency.

A slope does not exclude a concrete slab foundation. I also consider our house a slab-on-grade house, even if the ground floor supports the slope. So why add a basement? No, not a basement, but a lower ground floor. A slope rules out a slab-on-grade foundation, even if you correctly call your lower ground floor the ground floor (meaning the entrance level). The plot of the original poster simply does not allow for discussion here; a partially slope-embedded full-height plinth level ("daylight basement") is clearly required. Ignoring the slope with an excessive retaining wall would definitely be a bad idea here.
